Patented Dec. 31, v1935 PATENT OFFICE INTERNAL comps-non ENGINE Thomas E. Quick. Wichita, Kans. Application June 10, 1933, Serial No. 675,249 '1 Claim. (Cl.'12332) My invention relates to improvements" in internal combustion engines. I

The object of my invention is to provide increased efliciency of ignition in an internal combustion engine at the high compression point by creating turbulent action of the fuel under high velocity. I

A further object of my invention is to provide a reduced combustion chamber in the head of the cylinder, and means on the head of the piston coacting therewith creating high velocity at the maximum compression stroke of the piston.

A still further object of my invention is to provide a means applicable to the piston or cylinder head that will function with equal efliciency with respect to turbulent mixing velocity and breaking up of the fuel compound at the maximum moment of compression.

A still further object of my invention is to provide an apertured elementcarried by the piston or stationarily arranged in the cylinder head through which compressed fuel will circulate at the high compression point created by the piston movement as it advances toward the head of the v cylinder.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of this specification, and in which like characters will 40 Fig. 5 is a similar view to Fig. 1 modified by a conical head and piston.

Fig. 6 is a sectional view 'thru a modified form of cylinder showing the combustion chamber eccentrically positioned and a depression in the tending apertured flange of the combustion chamber.

I Fig. 7 is an upper end view of the piston shown in Fig. 6.

My invention herein disclosed consists of a cylinder I having a combustion chamber 2 in the closed end thereof. The said combustion chamber may be arranged with an outwardly extending flange 3 concentric with the axis of the chami5 ber and having a plurality of apertures l extendhead of the piston to receive the downwardly exing through the, flange and spaced therearound as shown in Fig. 1, or the saidflange may be carried by the piston as will be later described.

In conjunction with the above, I have arranged a piston 5 having an annular depression 6 in the 5 head thereof in which the said flange is insertable to its full length, the view in Fig. 1 showing a partial stroke as the piston approaches its extreme position.

In Fig. 3 is shown a similar cylinder I having a 10 combustion chamber 1 concentrically positioned in the head of the cylinder. Said chamber has an opening communicating with thecylinder reduced in size to form a throat in which an upwardly extending flange 8, integral with the pis- 15 ton 9, is insertable therein at each reciprocating movement of the piston. Said flange has a plurality of apertures in passing through the wall thereof, the function of which will hereinafter be explained. Q

The two latter described cylinders have horizontal inner surfaces transverse to the axis of their respective cylinders, and the top face of the piston in each coincides with the lower face 01 the cylinder head. Furthermore, a conventional 25 type of valve H for controlling the air intake and exhaust, and also a fuel injector I2 is shown in v Figs. 1 and 3.

In Fig. 5 the cylinder I has a frusto-conical head I 3 and the piston 5 has a frusto-conical piston head I to coincide therewith- This type of cylinder and piston has a similar combustion chamber and annular flange insertable therein as shown and described in Fig. 3, the latter being 85 a modification.

In Fig. 6 the cylinder I has a combustion chamber l5 eccentrically positioned and has a flange l6 outwardly extending and being apertured approximately as shown at H, the said flange coincides with said walls of depression l8 in the piston 40 head and is insertable therein at the maximum stroke of the piston.

The two latter described modifications of the cylinders have injectors l9 communicating with their respective combustion chamber, the source of fuel supply not shown in the drawing but properly arranged for voperativeness'. There is also arranged ports 20 for intake and exhaust. Fig. 1 has similar ports 20 arranged in the wall of the cylinder coacting with its valve ll, said ports having free communication with the cylinder at the maximum outward stroke of the piston.

The arrangement of the apertured flange provides for turbulent action of'the compressed fuel thoroughly mixing the sweat the maximum ignited which will accomplish the desired result of economy in fuel, efficiency of combustion, and power.

While I have shown an air cooled cylinder, the same principle will apply to a jacketed or water cooled cylinders, also the apertures of the flange may be. radially or tangentially bored thru the same with respect to the center for the turbulent action, and such other modifications may be employed as lie within the scope of the appended claim.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

In an internal combustion engine, the combination of a cylinder and a piston, the head end of said cylinder having an internal surface portion formed as a frustum of a cone with the base diameter equal to the diameter of the cylinder, an ellipsoidal combustion chamber formed in the top portion of said head end and communicating with said surface portion through a pcripheral opening concentric with upper surface of said frustum and of a diameter less than the major axis of said chamber, a fuel injection nozzle extending into said combustion chamber axially thereof, a frusto-conical head for, said piston, and an apertured annular flange formed 10 integral and concentric with said piston head and extending upwardly thereof, the apertures in said flange being formed in two rowslying in parallel planes spaced along the axis of the cylinder, one located near the upper end of said flange 15 THOMAS E.
